COHN-PLANTEFh.

Specification of Letters Patent.

ratentecl. June 5, 1906. I

To all whom it may concern:

Be it known that I, SOLOMON GRANT Lona, a citizen of the United States,residing in Washington townshi in the county of Hamilton and State ofihdiana, have invented new and useful Im rovements in Qorn-Planters; andI do dec are the followm to be a.

full, clear, and exact descri tion 0 the invention, reference being hato the accompanying drawings, and to the letters of reference markedthereon, which form a part of this specification.

The invention has reference to horsepower machines for planting corn orother seed rain in rows elther drilled or checkrowef, and the inventionhas particular reference to the means for opening the furrow anddropping the grains therein, especially for planting in check-rows.

Objects of the invention are to provide simple and relativelyinexpensive mechanism in corn-planters for planting in check-.

rows without requiring the intricate and .somewhat troublesome check-rowmechanism and line-wires heretofore generally employed and to providedurable and economica check-row mechanism which may be adapted to beemployed in drilling seed into the round.

ith the above-mentioned and minor objects in view the invention consistsin improved dropping mechanism for corn-planters com rising seedzguidesand drop ers connects with the see boxes, the latter avingseed-measuring devices therein, wheels mounted on the seed-guides foropening the furrows and o erating the seed measurin and dropping evicesto drop the seed, an mechanism between the wheels and the seed measuringand dropping vices; and the invention consists, further, 1 the novelparts and the combinations and arrangements of parts, as hereinafterparticularly described and claimed.

Referring to the drawings, Figure 1 is a side .elevatlon of acorn-planter constructed substantially in accordance with the invention;Fig. 2, a top plan thereof; Fig. 3, a transverse vertical sectional viewthereof on the line A A in Fig. 1; Fig. 4, a fragmentary Fig. 1; Fig. 6,a fragmentary vertical sectional view approximately on-the line D D inFig. 3; Fig. 7, a horizontal sectional view on the line E E in Fig.- 5;and Figs. 8 and 9 detached parts of the dropping mechanism.

Similar reference characters in the several figures of the drawingsdesignate corresponding eleme; its r features.

11 the drawings, a and a designate the carrying-wheels cf thecorn-planter, the wheels being designed to cover the deposited corn; 6,the axle for the wheels; 0, the drivers seat; F, the rear frame that ismounted on the axle and supports the seat; G, the tongue for guiding themachine; H, the forward or runner frame that is attached to the tongueand connected by pivots d and d to the rear frame; I, the leveroperating in connection with a quadrant e and havin an arm f connectedwith the rear end 0 the tongue G for elevatin ordepressing the rear endof the forwar frame H, and thereby the wheels that effect operation ofthe seed-dro ping mechanism. The above mentionede ements maybe variouslyconstructed in detail.

In practically carrym out the invention a pair of seedboxes J and J ofsuitable construction are mounted suitably on the for- Ward frame H andhave a ertured bottoms K and K, respectively. seed-plate L of suitableconstruction is mounted rotatively on the bottom of each seedbox and hasa suitable number of seed-pockets g therein, the seed-plates havingbevel gear-wheels M and M attached thereto that are arranged beneath theseedbox-bottoms, the latter having each an aperture h therein, throughwhich the seeds may drop from the pockets 9 when a pocket is oppositethe aperture, there being a cover or cut-offal attached to the seedboxabove the seed-plate L above the aperture h to revent seeds fromentering a pocket 9 while t e measured seeds may be drop ing therefromthrough the aperture 72,. eedguides N and N are attached to the bottomsof the seedboxes and have each a channel h communicating with theaperture h of the bottom of the seedbox. The seed-guides extenddownwardly a suitable distance, so as to a proach the ground for guidingthe seeds to t e furrow, and each one is provided with a boss 7', thatsupports a stud-axle O at one side and a stud-axle O at the oppositeside of the seed-guide. The stud-axle 0 projects of the seed-guide N.

A rock-shaft S is mounted horizontal] in the frame H, and two bevelgear-whee s T and T are mounted rotatively thereon and mesh with theear-Wheels M and M for 0 erating the see lates. A ratchet-wheel isattached to eac Wheel T and T for the operation thereof intermittently.Arms V and V are attached to the rock-shaft S, and each arm has a pawl Zenga ing an adjacent ratchet-whee An arm l is attached also to therock-shaft S and extends into the path of the end of the trip-arm to beintermittently enga ed thereby durin the rotation of the whee P, whichwith t e mechanism above described will cause the seeds to be measuredand dropped into the seed-guides.

In order to accurately drop the seeds for hills without scattering theseeds, separate dropping a paratus is provided comprising two arms I?and X, that are secured to the rock-shaft S, two arms Y, pivoted at endsthereof to the seed-guides N and N, and two gates Z, that are mounted atthe bottoms of the seed-guides and connected to the opposite or freeends of the arms Y. A stiff spring m forms a ielding link connectionbetween each arm or X and an arm Y, and a relatively weak spring itconnects each arm Y with the frame H by means of a bracket 1) forretracting the arms Y to open the ates and also for retracting the arm Wan the arms X and X. It will be seen that when the arm W is movedforwardly by the triparm Q the gates Z will quickly close, and then thespring 171. will permit the arm W to move farther, so as'to rotate theseed-plates sufliciently to drop the seeds into the seed-guides to bemomentarily held b the gates. After the arm W is released by t e tri-arm Q passing beyond it the spring n W11 retract the connections andopen the seedates suddenly, suitable stops of course eing rovided forgaging the amount of travel 0 the rock-shaft and arms carried thereb Itwill be understood that the diameter of the wheel P will be about onefoot for planting in hills three feet a art, and it is designed that thewheels P and f and the disks R and R shall run into the soilsufficiently deep to 0 en furrows intowhich the seeds may be p anted. v

In practical use horses are to be hitched to the machine, and when onhighways the lever I may be drawn backwardly to elevate the framecarrying the wheels P P and the disks above the ground. When be 'nningto plant a row of corn'for hills in chec -row order, the wheel 1? is tobe turned by hand, while the machine is at rest until seed for a hill isdropped at the desired spot. Then the machine may proceed across thefield, the wheel P, while assisting in opening a furrow or trench,measuring the d1stances for the hills and causing the seeds to be droped at the desired uniform distances apart w ich is accomplished b reasonof the wheel the soil at al times and not dro iping into low spots norrisin over lum s or 'gh spots on the ground, an the whee may be forcedto enter the ground more or less by manipulating the lever I, as will beunderstood. The wheelsaand a follow, as usual and cover the seeds in thefurrows. While t e wheel P rotates once in each revolution thereof thetrip-arm Q will engage the arm W, the gates thereby bein closed inadvance of the movement of a fu 1 pocket 9 of seeds to the aperture h inthe seedbox-bottom, so that the seeds when they fall into the channel hwill be stopped by the gates Z and held momentarily, so as to bunchthem, after which they will be drop ed all together, When it is desiredto drill the see s, the gates and their connections may be removed, andadditional trip-arms Q may be applied, so as to operate the seed-platesas often as may be desired.
